The easiest digital stamp card software for local businesses

The stamp card works. The paper doesn't.

Stamp cards are one of the most proven loyalty tools around. The mechanic is simple and it works — customers come back because they're working toward a goal. The principle is sound.

The problem is the medium. 39% of customers abandon paper stamp programs because they lose the card (Statista). Others leave it at home. And as a shop owner, you have no idea how many cards are actually in circulation — or how many ended up in the bin.

Digital stamp cards change the medium, not the idea. The card is always there — on the customer's phone. No losing it, no forgetting it, no starting over. Customers who stopped collecting because they lost their card? They come back.

39% of customers abandon paper programs — because they lost the card.

What your customer experiences

No app download. No account. No password. Your customer scans once — and has a digital stamp card, instantly.

1. 1

   First visit

   The customer scans the QR code in your shop — or taps the NFC stamp — and gets their digital loyalty card immediately. It opens directly in the browser, no download required.

2. 2

   Save the card

   With one tap, the card goes into Apple Wallet or Google Wallet. Always accessible — even offline — and not lost in a browser tab.

3. 3

   Collect stamps

   A stamp is added on every visit. Customers see their progress at a glance — and research shows: the closer the goal, the more often they come back. That's not a marketing claim, it's documented psychology.

4. 4

   Redeem the reward

   When the card is full, they redeem right on their phone — no paper, no code, no hunting around. The card resets and the cycle starts again.

For your staff: simpler than making coffee

Stamping takes two to three seconds. Scan a QR code, hold an NFC stamp to the phone, or enter a PIN — done. No training required. Most staff figure it out without being shown.

Summa runs in the browser on whatever device you already have behind the counter — tablet, laptop, or phone. No installation, no new hardware. If you can log into a website, you can run Summa.

The dashboard shows you how often stamps are issued, how many cards are active, and when rewards are redeemed. No more guessing — you can see whether your program is working.

Three ways to stamp — you choose what fits

There's no right or wrong method. Which one works best depends on your counter and your daily flow.

The card lives on the phone — not in an app

Only 12% of smartphone owners with loyalty memberships have ever downloaded a loyalty app (Bond Brand Loyalty). The rest don't bother — too much friction for too little value.

Summa cards don't need their own app. They run in the browser and save to Apple Wallet or Google Wallet with one tap — right where customers already keep their tickets, passes, and cards. Always accessible, even without an internet connection.

If someone gets a new phone, they recover their card by email. No lost progress, no starting over.

What customers collect — examples by business type

The best reward has high perceived value and low actual cost. A free coffee costs you 20–30% of the sale price — but it feels like a real gift to the customer.
